Beautiful color and the lighting is superb. The subject is very peaceful and so, evokes a sense of calm.
The only thing I'm not sure about is the structure being right at the horizon line. I know you probably lined it up purposely but I feel it would be better if the you were able to take it from a lower POV and place the structure into the sky with the horizon line just below. Since they're silhouettes, I feel that they are better suited there and they won't conflict with the horizon either. Would it even be physically possible to shoot from a lower perspective?
Then again, maybe the clouds in the sky would be too busy a background for the structures?
...not that I don't like the photo. I'm just giving my thoughts. The object being at the horizon line makes me uncomfortable (if you can call it that). I hope it helps.
